Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Bpmn-replace-element-loader 插件使用说明

依赖库:bpmn-js , bpmn-js-properties-panel

官方文档中并没有提供直接操纵BpmnElement对象和BpmnBusinessObject对象的方法,为了满足一些业务需求,我将其提取出来挂载在window.bpmnPanel对象中。这样我们就可以在自己的业务逻辑中往BpmnElement对象和BpmnBusinessObject对象中添加自定义数据。

每当用户操纵Bpmn组件时,window.bpmnPanel.bpmnPanelElement和window.bpmnPanel.bpmnPanelBusinessObject 都会自动更新。我们只需要调用API进行赋值即可。

针对Vue 我使用vm.$set将其挂载在window.vm.$children[0]中以实现响应式更新。使用watch可以很方便的监听对象的变化并进行业务逻辑的处理。

如果你使用其他框架,那么你需要自己实现监听window.bpmnPanel对象。

使用方法

//给window一个bpmnPanel属性
window.bpmnPanel={};

//Vue-cli3 vue.config.js
module.exports = {
//...
chainWebpack(config) {
    config.module
      .rule('bpmn-replace-element-loader')
      .test(/\.js$/)
      .use('bpmn-replace-element-loader')
      .loader('bpmn-replace-element-loader')
      .end()
  }
};

强制修改Task类型

//Task type
const TaskList = [
  "bpmn:Task",
  "bpmn:ServiceTask",
  "bpmn:SendTask",
  "bpmn:UserTask",
  "bpmn:BusinessRuleTask",
  "bpmn:ScriptTask",
  "bpmn:ReceiveTask",
  "bpmn:CallActivity",
  "bpmn:TimerEventDefinition",
  "bpmn:SignalEventDefinition",
  "bpmn:MultiInstanceLoopCharacteristics"
];
// 例子:默认Task->UserTask
const bpmnPanel = window.bpmnPanel;
const element = bpmnPanel.bpmnPanelElement;
bpmnPanel.replaceElement(element,{type:'bpmn:UserTask'})

添加Documentation属性

const bpmnPanel = window.bpmnPanel;
const element = bpmnPanel.bpmnPanelElement;
const command = bpmnPanel.bpmnPanelElementDocuEntry.set(element, {documentation:"your data"});
bpmnPanel.bpmnPanelCommandStack.execute(command.cmd, command.context);

添加Expresstion属性

const bpmnPanel = window.bpmnPanel;
const element = bpmnPanel.bpmnPanelElement;
const commands = bpmnPanel.bpmnPanelConditionalEntry.set(element, {conditionType: "expression",condition:"your data"});
commands.forEach(command => {
  bpmnPanel.bpmnPanelCommandStack.execute(command.cmd, command.context);
});
